This single still is from the widescreen version of ?Matriculated?, one of the Animatrix animated shorts. It has been considerably scaled back from the original material.
Continuing on from the still Large Image Display: Animatrix: Matriculated: Designed to Run, this single shot looks at how the robots respond when they encounter a threat they ordinarilly cannot handle. The antenna that we could see above the eye sensors in the previous shot, are now on the bottom of the robot.
They have literally turned on their heads, and now we see that those 'antenna' that seemed far too large for any possible purpose, are a complex form of shape metal and artificial muscle - both technologies being experimented with today. Yhey are capable of supporting the robot's weight, and moving more slowly, slithering like a snake, or coiling for a spring.
This brings their four legs, previously on the ground, into play as attack arms. Now their previously demonstrated dexterous ground movement takes on a different meaning - extremely dexterous attack arms. In addition, the reason for their slender design now becomes apparent, as the design puts a lot of force behind sharp, slender jabbing limbs.
Whilst modern robotics cannot duplicate these designs, nothing about them is pure fantasy, and all is based in actual science. Thus, we may well be seeing robots not too dissimilar to these, in the decades ahead.
